HP XP P9500 Storage - Manual (Page 144)

secondary site The physical location of the storage system that contains the primary volumes of remote replication
pairs at the main or primary site. The storage system at the secondary site is connected to the
storage system at the main or primary site via remote copy connections. The secondary site can
also be called the “remote site”. See also primary site.
secondary volume The volume in a copy pair that is the copy. The following HP products use the term “secondary
volume”: Remote Web Console, Snapshot, Business Copy, Business Copy Z, Continuous Access
Synchronous, Continuous Access Journal, Continuous Access Journal Z, and External Storage
Access Manager.
See also primary volume.
seq. sequential
service information
message (SIM) SIMs are generated by a RAID storage system when it detects an error or service requirement.
SIMs are reported to hosts and displayed on Remote Web Console.
severity level Applies to service information messages (SIMs) and Remote Web Console error codes.
shared volume A volume that is being used by more than one replication function. For example, a volume that
is the primary volume of a Continuous Access Synchronous pair and the primary volume of a
Business Copy pair is a shared volume.
sidefile An area of cache memory that is used to store updated data for later integration into the copied
data.
SIM service information message
size Generally refers to the storage capacity of a memory module or cache. Not usually used for
storage of data on disk or flash drives.
SM shared memory
snapshot A point-in-time virtual copy of a Snapshot primary volume (P-VOL). The snapshot is maintained
when the P-VOL is updated by storing pre-updated data (snapshot data) in a data pool.
SOM system option mode
source volume
(S-VOL) The volume in a copy pair containing the original data. The term is used only in the earlier version
of the Remote Web Console GUI (still in use), for the following HP products: Business Copy Z,
Dataset Replication for Mainframe, IBM FlashCopy.
space Generally refers to the data storage capacity of a disk drive or flash drive.
SSB sense byte
SSID (storage) subsystem identifier. SSIDs are used as an additional way to identify a control unit on
mainframe operating systems. Each group of 64 or 256 volumes requires one SSID, therefore
there can be one or four SSIDs per CU image. For P9500, one SSID is associated with 256
volumes.
sync synchronous
system option
mode (SOM) Additional operational parameters for the RAID storage systems that enable the storage system
to be tailored to unique customer operating requirements. SOMs are set on the service processor.
V version; variable length and de-blocking (mainframe record format)
V-VOL virtual volume
V-VOL
management area Contains the pool management block and pool association information for Snapshot operations.
The V-VOL management area is created automatically when additional shared memory is installed
and is required for Snapshot operations.
VB variable length and blocking (mainframe record format)
view mode The mode of operation of Remote Web Console that allows viewing only of the storage system
configuration. The two Remote Web Console modes are view mode and modify mode.
virtual device
(VDEV) A group of logical devices (LDEVs) in a RAID group. A VDEV typically consists of some fixed
volumes (FVs) and some free space. The number of fixed volumes is determined by the RAID level
and device emulation type.
virtual volume
(V-VOL) The secondary volume in a Snapshot pair. When in PAIR status, the V-VOL is an up-to-date virtual
copy of the primary volume (P-VOL). When in SPLIT status, the V-VOL points to data in the P-VOL
